it is af-urther 'object of the invention to provide a pump of thecharacter described wherein the piston driving mechanism may be readilyadjusted to control the stroke of the pistons.

(other objects andadvantages will be "apparent from the followingspecification which is illustrated by the accompanying-drawings,wherein:

Fig-ure'l is a horizontalsectional view takenon the line of Figure "2;and

Figured is a vertical sectional view taken -on the'line 2-4 of "Figure-1.

Referring now more particularly -'to the drawings wherein like numeralsof reference designate the same parts in each of the figures, thenumeral 1 designates a gear case which is tubular in form and which issupported on any suitable base, as '2. Mounted on the gear case andsuitably secured thereto there is .a frame comprising a supporting plate3 with the concentricupstanding outer and inner annular flanges .4 and 5.secured thereto in any preferred manner.

Extending through flanges and suitably secured thereto there are aplurality of radial cylinders wherein the pistons I are mounted toreciprocate.

These pistons are connected .to a ring 8 by means .0! the connectingrods 8 whose outer ends are pivoted to the respectivepistons andwhosefinner ends are pivotal'ly connected to said ring 8.

Within the gear case I and fastened to the plate 3 thereis a bearing 10in which the vertical shaft 11 is mounted to rotate.

Fixed on the lower end of the shaft ILI thereis ala'rge bevel gear wheell2 which is in mesh and driven by a bevel pinion 113 which is fixed on i=-by a series of loolts I 8 or said segment [1 may he otherwiseadjust-ably secured "to the dis'c Ni. I h'e segment i! *is circular inshapebu't it is eccentric with respecttd-the disc 16 andby'loosening thebolts l8 said segment may be adjusted dircum- 'ierentially about thedisc I 6.

.said'idisc' 'l fiandthe segment F-I for-n1"an-reticentric which rotateswith-the shaft H. 4

This :ecc entr-ic is mounted-w ithin thering B and said ringand-eccentric have registering raceways inwhich the anti-'frictionballs19 are mounted.

The segment I' LJ-the ring8 and the 'balls I 9 may be assembled byleaving agate -inpne of said adjacen-t parts for inserting the "bails,which gate may then be closed, in any preferred manner, by welding orotherwise.

As the eccentric rotates with "the shaft H the "ring 8 "will heosciilate'd and will impart horrespending strokes to'the pistons in thecyI-inders 3.

Connected to the outer ends of the respective cylinders are thema-ni'fold's 2-0.

"Leading into corre'sponding en'd-sof the inanii'oids "2'0 are theintakepipes -21 which are controlled bythe inwardly opening intakevalves '22. Leading "outwardly from the opposite ends of said manifoldsare the 'outlet 'pipes 23 which are controlledby the 'correspondingoutlet valves 24.

The intake =pipes 2l are-connected into the'common iriletmanifold 25with which the inletsuction line "26 is connected and the outlet pipes23 are tormented into a cominonoutlet manifold TI into which thedischarge line 28 is connected.

Accordinglyupon-rotation ofthe-eccentric, fluid will be constantly drawnin through -the suction "line 26 and discharged through the dischargeline 28 and the capacity cfthe pumpimay'loe regulated by theadj ustmentof the'ec'centric segment W, as

"hereina'bove explained.

An an-ti-Trictionbearing assembly!!! 'i's'provid'ed between the hub ofthe :dis'c B .and 'the frame of thepump.

The drawings and description are illustrative merely While the "broadprinciple of the invention will he defined by the appended claims.
